HDMI to DVI: Solutions for HD Monitors

July 31, 2012

HDMI-to-DIVHDMI and DVI are similar when it comes to the quality of image they produce. They use the same encoding scheme so you may directly connect a DVI source to an HDMI monitor and vice versa with or without the need of a converter box. The only difference is that an HDMI carries audio and video inputs while a DVI can only handle video.

Why They Are Used

The DVI and HDMI all deliver digital video standards that support numerous resolutions. DVI has more extensive uses because it is the most common digital video cables seen in computers and LCD monitors today. It can stream of up to 1920 x 1200 HD video with a resolution of 2560 x 1600 pixels, max. Hence DVI cables are used for lower resolution devices. The biggest problem with a DVI cable is that it does not support HDCP. Without HDCP, you will not be able to playback full HD Blu-rays and other HD content.

In comes HDMI and all hindrances will be washed away. HDMI is the default cable used in HDTVs, Apple TV, and Blu-ray players and a host of new computers and video cards. These cables can stream up to 1920 x 1200 HD video and 8 channel audios simultaneously. Other than that, HDMI cables support HDCP encryptions too.

You can connect DVI to an HDMI port with the use of a small digital converter. But since DVI does not support audio, you will need to use a separate audio cable when transferring data via an open HDMI port.

You will need to use an HDMI to DVI cable if you are trying to connect two devices that have separate ports. Older digital devices usually use DVI while newer technologies use HDMI.

Performance

When you’re transferring data from an HDMI-supported device to a DVI port, expect a slight change in audio. This is because you will be converting the audio to lower versions to have it played on the DVI device. This goes the same with the resolution and HD capability of the data you transferred.

The biggest change that you are to encounter is that you will not be able to do playbacks on full HD because as mentioned above, DVI does not support HDCP. All-in-all, cable quality has a direct influence on the output as shown on the receiving device.

Level of Quality

It is assumed that digital transfers are not error-free. HDMI and DVI are not subject to error correction. This means that if a technical difficulty happens that would result to the loss of data, then the information would be lost forever too. That is why you will need well-made cable over short distances and better ones for long distance connections.

Another thing to remember is that very few cables produce outputs at their native resolutions. Always expect some scaling up to scaling down to happen. You will need to check on the receiving device’s hardware too when it comes to color rendering.

Best Brands Available

The most widely marketed HDMI to DMI cables today are those bearing the brand of Belkin. However, Belkin cables are quite expensive. You will do well with generic ones though granted that they come with warranty.
